CROSS REFERENCE TO RELATED APPLICATION

This application is a non-provisional application of U.S. Provisional Application No. 62/370,337 filed on Aug. 3, 2016, entitled “AFTERMARKET HEAD UNIT INSTALLATION KIT FOR USE WITH, INTER ALIA, LEGACY KNOB ASSEMBLIES, DETENTS AND DETENT RETAINERS”.

FIELD OF TECHNOLOGY

Aspects of the disclosure relate to kits for adapting an automobile for replacement of an Original Equipment Manufacturer (OEM) car stereo (referred to, in the alternative herein, as a “head unit”) with an aftermarket car stereo or head unit.

The term “OEM head unit” may be understood herein to refer to electronic devices capable of playing audio and/or displaying video media, and includes, without limitation, each of the foregoing components either individually or in combination that are produced by the Original Equipment Manufacturer. The term “aftermarket head unit” may be understood herein to refer to electronic devices capable of playing audio and/or displaying video media, and includes, without limitation, each of the foregoing components either individually or in combination that are produced by an aftermarket manufacturer.

BACKGROUND

Standard equipment on most cars includes an AM/FM radio tuner, tape deck, and/or compact disk (CD) player. Digital media players (e.g., mp3 players, DVD players, minidisk players), CD changers, satellite radio tuners, navigation systems and computers may also be purchased for an automobile as OEM or aftermarket parts.

As more and different aftermarket head unit components become available, people want the flexibility to customize and/or upgrade their existing head unit equipment to take advantage of the new innovations in car audio equipment.

This flexibility may be limited by the fact that many new vehicles have an OEM head unit integrated with one or more user interfaces, such as head unit knobs or other similar user interface equipment. Upon removal of the OEM head units, the user interfaces need to be removed as well.

Typically, because of size mismatches between the OEM head unit and the aftermarket head unit, installation kits have been provided for enabling installation of aftermarket head units.

These kits have typically needed to provide such replacement interfaces because the OEM user interfaces were integrally related with the removed OEM head units. As such, one of the requirements of legacy kits was that the kits provide aftermarket head unit user interfaces to replace the removed OEM user interfaces that formed a part of the OEM head units.

Moreover, the OEM head units' interfaces have become more complex with time. As such, it has become more difficult to provide kits for use with aftermarket head units because of the level of complexity associated with the OEM user interfaces required to control the OEM head units.

As state above, often the user cannot remove the OEM head unit without replacing the OEM user interface mechanisms. In such circumstances, the replacement user interface mechanisms may be of a lesser quality and/or complexity than the OEM user interface mechanisms and, as such, reduce the quality of the user experience associated with the aftermarket head unit.

In addition, replacing, or substituting for, the highly-complex OEM user interface mechanisms may sharply increase the complexity, and cost, of kits for use with replacement OEM head units.

For these and other reasons, there exists a need for partial installation kits that allow aftermarket head units to be installed in vehicles, while keeping the complexity of manufacturing such kits to a minimum.

There exists a further need for providing installation kits that salvage user interfaces associated with OEM head units in order to reduce the complexity of fabricating the installation kits.

FIG. 1A shows a front view of a prior art, installed, OEM head unit 100 as may be installed on certain late-model Chevrolet Camaro™ automobiles. OEM head unit 100 may include one or more than one knob assembly 102. FIG. 1B shows a front view of the OEM head unit 100 with knob assembly 102 removed from the head unit. In typical OEM head units, knob assembly 102 may be removed from OEM head unit 100 by removing OEM head unit 100 from the dashboard of the vehicle and then unscrewing a plurality of screws (not shown in FIGS. 1A and 1B) which, when deployed, serve to fixedly attach knob assembly 102 to OEM head unit 100. The screws are installed (and removed) from the back of OEM head unit 100 and, therefore, would not be visible from the front view of OEM head unit 100. It should be noted, however, that screw holes 104 show exemplary holes into which screws may be inserted for attaching knob assemblies 102 to OEM head unit 100.

FIG. 1C shows an elevational view of a conventional OEM circuit board 114. Circuit board 114 includes a full-size front-on profile.

FIG. 2 shows an exploded view of a partial automotive head unit kit according to certain embodiments. FIG. 2 includes an installation kit 200 according to certain embodiments. Installation kit 200 may preferably enable installation of an aftermarket head unit in the location previously occupied by an OEM head unit. As is known in the art, installation kit 200 is preferably designed to make up for any volume and/or size mismatches between the volume occupied by the OEM head unit and the volume occupied by the aftermarket head unit.

Kit 200 preferably includes a door lock/unlock button 202 and a hazard light button 204. It should be noted that door lock/unlock button 202 and hazard light button 204 are preferably provided in kit 200 because, in the OEM system, an door lock/unlock button and an hazard light button are preferably mounted in the console associated with the OEM head unit. As such, the functionality associated with the OEM door lock/unlock button and the OEM hazard light button may preferably be replicated in kit 200 in order to preserve the functionality associated with the OEM door lock/unlock button and OEM hazard light button. Such functionality may preferably be associated with lock/unlock button 202 and hazard light button 204. Lock/unlock button 202 and hazard light button 204 may be mounted preferably in a center portion of printed circuit board 214.

It should be noted that while kit 200 is shown to replicate the door lock/unlock button and the hazard light button functionality, it should be understood that kit 200 may also be used to support various other or additional functionality associated with the portion of the console associated with the OEM head unit, such as electronic window buttons, etc., or any other functionality, without departing from the scope of the invention.

LCD display 206 may preferably be used to show a temperature reading, a clock reading or other similar type of reading from the vehicle.

Screws 208 and 210 may be used for securing printed circuit board 214 to panel 212. It should be noted that printed circuit board 214 may preferably replicate the operation of OEM circuit board 114 that is associated with the OEM knob assemblies (see FIG. 1, element 114 and element 102). It should be noted that circuit board 214 has a reduced-front-on-profile in comparison with the conventional circuit board 114 shown in FIG. 1C.

It should be noted that in some kits, printed circuit board 214 may preferably incorporate an irregular shape 215 at the bottom of circuit board 214. Irregular shape 215 preferably provides a pass-through for a portion of detent retainer 225. Detent retainer 225, which, in certain embodiments, may preferably be salvaged from the OEM head unit, provides a spring-loaded male member 229. Spring-loaded male member 229 preferably is mounted on male member support structure 227.

Male member 229 is configured to engage, typically one at a time when a knob is turned, a series of detents (not shown) on the back of OEM knob 205. By engaging the detents on OEM knob 205 as knob 205 is turned, male member 229 preferably creates a clicking as the detent springs in and out of the detents on the back of the knob. In other words, the OEM knob rides on male member 229. Male member 229 moves up and down on the detents of the knob as the knob rotates.

Left bracket 216 and right bracket 218, upon installation of kit 200, may preferably lock kit 200 to side walls of the cavity (not shown) in the vehicle dashboard previously occupied by the OEM head unit. Subdash clips 226 preferably couple the top portion of kit 200 to the lip of the cavity left in the automobile by removal of the OEM head unit.

Lock/unlock button 202 for and hazard light button 204 may preferably engage lock membrane 220 and hazard membrane 222, respectively, when mounted in panel 212.

Kit 200 includes a large roughly rectangular aperture 201 in panel 212. This aperture is for mounting a screen of an aftermarket head unit. Such a screen may provide navigation functionality when the aftermarket head unit supports such functionality. In addition, or in the alternative, such a screen, when implemented as a touch screen, may preferably support stereo functionality such as pre-set radio station tuner knobs or any other suitable functionality associated with a touch screen. The reduced profile circuit board 214 enables the installation of a larger than OEM head unit—e.g., a double DIN head unit. This is because the height of the OEM circuit board has been reduced in order to accommodate a larger than OEM size head unit.

Kit 200 may also preferably include two substantially circular apertures 203 in the front face of panel 212. Circular apertures 203 preferably are configured to receive and engage OEM knob assemblies 205 in such a way as to enable OEM knob assemblies 205 to electronically couple to circuit board 214. As such, the functionality associated with OEM knob assemblies 205 may preferably be maintained following installation of kit 200.

Kit 200 may also include optional pocket 224. The size of pocket shown in FIG. 2 is what is known in the art as a single DIN size. When the aftermarket head unit that is replacing the OEM head unit is a single DIN size, then the aftermarket head unit only occupies approximately the top half of the rectangular aperture shown in the front of kit 200. Accordingly, the bottom half of rectangular aperture 201 shown in the front face of kit 200 is not occupied. Optional pocket 224 may preferably be inserted into the other half of rectangular aperture 201 not occupied by the aftermarket head unit. Optional pocket is shown by itself as pocket 402 in FIG. 4.

PCB leveler 228 may be used to level display 206 and may be affixed in place by screws 230.

FIG. 3A-3F shows various views of illustrative panel 300 for use according to certain embodiments. FIG. 3A shows a side view, taken from a first angle, of illustrative panel 300 according to certain embodiments. FIG. 3B shows a top view of the illustrative panel 300 according to certain embodiments. FIG. 3C shows a front view of panel 300 according to certain embodiments. FIG. 3D shows a bottom view of panel 300 according to certain embodiments. FIG. 3E shows a front view, taken from a second angle of panel 300 (shown in FIG. 3A), according to certain embodiments. FIG. 3F shows a front view, taken from a third angle (shown in FIG. 3A), of panel 300 according to certain embodiments.

It should be noted that the twin circular apertures 302 on the front of panel 300 are configured to accept the knob assemblies (see FIG. 1B, element 102) from the OEM head unit. As each of twin apertures 302 preferably have a diameter of about 2.4″, or other suitable size, in order to accept the legacy OEM knob assemblies following removal of the knob assemblies (see FIG. 1B, element 102) from the OEM head unit.

Furthermore, panel 300 may include two or more plastic towers 306 and 308 (shown only in FIGS. 3B and 3C for simplicity) which are adapted to engage detent retainers 225 (shown in FIG. 2). Detent retainers 225 provides a spring-loaded member such that turning the knob, each of the knobs that includes detents about the perimeter of the knob, momentarily clicks the spring-loaded mechanism. This clicking type of turning is place of providing a smooth turn. A clicking mechanism, which preferably allows the knobs to rotate in a stepwise fashion instead of a smooth turn, is more commonly found in automobiles and other moving vehicles in order to prevent accidental rotation of the knobs.

FIG. 4 shows an illustrative optional head unit pocket 424 for use according to certain embodiments. As mentioned above, optional head unit pocket 424 may preferably be used when the aftermarket head unit being installed is a single DIN head unit. However, when the aftermarket head unit being installed is a double DIN head unit (which occupies roughly twice the vertical height of a single DIN head unit), then the optional head unit pocket 424 cannot be used because the entire aperture on the front face of installation kit 200 (shown in FIG. 2) is occupied by the double DIN aftermarket head unit. It should be noted that the front face of the double DIN aftermarket head unit may be implemented as a screen that is capable of displaying a navigation map as well as any other suitable features supported by the double DIN head unit.

FIG. 5 shows an illustrative subdash clips 526 for use according to certain embodiments. Subdash clips 526 may preferably be used to couple the top portion of kit 200 to the lip of the cavity left in the automobile by removal of the OEM head unit.

FIG. 6 shows an illustrative OEM knob detent retainer 625 according to certain embodiments. Such a detent retainer 625 may preferably be salvaged from the OEM head unit and placed on installation kit 200, much the same way as OEM knob assemblies 205 may preferably be salvaged from the OEM head unit and placed on installation kit 200. OEM knob detent retainer 625 preferably includes detent retainer support structure 627 and spring-loaded male member 629 (spring not shown). As discussed above, male member 629 preferably engages detents on the back of knob 205 as the knob 205 is turned, thereby creating clicking sounds—and preventing the knob from spinning unintentionally.
